Description

Technical Field

[0001] The invention relates to the technical field of concrete vibration, in particular to a concrete specimen forming and vibration device. Background Art

[0002] In the process of building construction, in order to detect whether the strength grade of concrete meets the design requirements, it is often necessary to randomly sample the concrete at the pouring site of the construction site and make concrete test blocks. By testing the strength of the concrete test blocks, it can be judged whether the strength grade of the concrete in the construction process meets the requirements. In the process of making concrete test pieces, it is usually necessary to go through processes such as vibration, curing, and demoulding. Among them, the vibration process of concrete test pieces is a more critical step in the production of concrete test pieces;

[0003] In the prior art, when using a vibrating device for concrete specimens, a worker pushes a wheelbarrow carrying concrete to one side of the vibrating device, and then usually uses a shovel to scoop up concrete from the wheelbarrow and put it into a specimen mold. Since the specimen mold opening is small and the specimens are usually produced in large batches, manually putting concrete into the mold is not only time-consuming and laborious, but also there is a situation where a large amount of concrete falls outside the specimen mold during the transfer by the shovel.

[0004] In addition, the prior art usually places the specimen mold directly on the vibrating station, and during the loading and vibrating process, the mold and the vibrating station are easily offset, resulting in the need to manually adjust the position of the mold multiple times during the vibration process, resulting in poor vibration effect and greatly reducing the efficiency of the vibration.

[0005] The above contents are only used to assist in understanding the technical solution of the present invention, and do not constitute an admission that the above contents are the closest prior art. Summary of the invention

[0056] Compared with the prior art, the present invention has the following beneficial effects:

[0057] 1. The present invention can complete the alignment of the first clamping shaft and the second plug hole by guiding the first clamping shaft into the terminal end of the internal groove through the guide frame, which is convenient and quick.

[0058] 2. The present invention drives the conveyor belt upward through the driving roller by the first driving motor, and the conveyor belt drives the limiting guide rod to move along the track of the guide groove through the base, and the limiting guide rod drives the support plate to transmit upward obliquely through the fixed block, and the support plate drives the bucket from the bottom of the bracket to the top of the bracket through the lifting plate and performs the overturning and unloading operation. The overturned concrete is poured into the guide hopper for caching, thereby achieving the effect of automatic loading of concrete, without the need to shovel the concrete from the small cart and put it into the specimen mold with a shovel, saving time and effort.

[0059] 3. The present invention adopts a method of separating the truck bed from the truck frame, which not only slows down the solidification speed of the concrete, but also prevents a large amount of concrete from falling when being loaded into the mold, thereby effectively saving a large amount of concrete.

[0060] 4. The present invention drives the lifting plate upward along the guide rod when the cylinder drives the lifting plate to move upward, so that the second gear that was not originally engaged with the teeth on the upper side of the second rack rod moves to engage with the teeth on the upper side of the second rack rod, so that the second rack rod drives the second gear to rotate, and the second gear drives the first pulley to rotate under the action of the belt through the second pulley, and the first pulley drives the first rack rod through the first gear to move from being completely located inside the first clamping shaft to having one end located outside the first clamping shaft, so that the first rack rod positions the upper end of the lower support bar, thereby avoiding the hidden danger of the bucket detaching from the lifting plate when dumping concrete.

[0061] 5. The present invention drives the driving gear to rotate through the first tooth portion, and the driving gear drives the rotating shaft to rotate through the fixed shaft. The rotating shaft drives the arc protrusion to press the clamping blocks against both sides of the mold, so that after the mold placed on the support is initially positioned by the second limit block, the clamping block can further clamp and position the mold, avoiding the position displacement of the mold from the support during subsequent vibration and smoothing work, greatly improving the efficiency of vibration and achieving good vibration effect.

[0062] 6. The present invention drives the driving seat to move along the guide rail through the driving mechanism, so that the driving gear moves to mesh with the second tooth portion. At this time, the second tooth portion drives the fixed shaft to rotate in the opposite direction through the driving gear, and the fixed shaft drives the arc protrusion to reverse through the rotating shaft, so that the arc protrusion switches from the original state of pressing the clamping block to the state of separation from the clamping block. At this time, the tightening spring presses the first limit block, so that the first limit block drives the clamping block to separate from the mold through the guide shaft. At this time, the mold can be removed from the support by the manipulator, thereby achieving the effect of automatic positioning of the mold throughout the entire process during the vibration and smoothing work, and automatically stopping the positioning after the vibration and smoothing work, so that the manipulator can flexibly remove the mold from the support.

[0136] It should be noted that if Figure 12-13As shown, the upper and lower ends of the outer side of the mold 100 of the existing concrete specimen are usually reserved with convex strips 1001, and the ribs 1002 are fixedly connected between the convex strips 1001 located at the upper and lower ends of the outer side of the mold 100. The present invention avoids the ribs 1002 from blocking the clamping block 224, and provides a clamping groove 2241 for accommodating the ribs 1002 on the side of the clamping block 224 corresponding to the mold 100. In this design, in the subsequent vibration process, the ribs 1002 and the clamping grooves 2241 fully cooperate, which can further play the effect of positioning the mold 100.

[0137] It should be supplemented that a vibrating frame 101 and a smoothing frame 102 are installed in sequence above the guide rail 231 along the moving direction of the driving seat 232. A vibrating rod 1011 is installed on one side of the vibrating frame 101, which is used for when the driving seat 232 transfers the mold 100 to the position directly below the vibrating rod 1011, the vibrating rod 1011 can automatically extend downward into the concrete contained in the mold 100 to perform vibration work. A smoothing rod 1021 is installed on one side of the smoothing frame 102, which is used for when the driving seat 232 transfers the mold 100 to the position directly below the smoothing rod 1021, the smoothing rod 1021 can automatically extend downward into the upper surface of the concrete contained in the mold 100 to perform smoothing work.

[0138] It should be noted that: Figure 2-Figure 4 As shown, in the specific implementation process of the present invention, when a worker loads concrete into the bucket 122 and pushes the bucket 122 to one side of the carrying mechanism 113 through the frame 121, initially, the bucket 122 is inserted into the first insertion hole 1231 in the upper support bar 123 through the second clamping shaft 1211 on the frame 121, so that the bucket 122 is positioned on the frame 121. When the worker needs to transfer the bucket 122 from the frame 121 to the carrying mechanism 113, the bucket 122 is continuously pushed toward the carrying mechanism 113. The frame 121 is configured such that the opening on one side of the guide frame 1241 is aligned with the first clamping shaft 1134, so that when the worker pushes the frame 121, the guide frame 1241 moves along the first clamping shaft 1134 to the terminal end of the inner groove of the guide frame 1241. At this time, the first clamping shaft 1134 is exactly coaxial with the second insertion hole 1242, and the alignment work between the first clamping shaft 1134 and the second insertion hole 1242 can be completed by only guiding the first clamping shaft 1134 to the terminal end of the inner groove through the guide frame 1241, which is convenient and quick;

[0139] like Figure 3-Figure 4As shown, then, the cylinder 1132 is started, and the cylinder 1132 drives the lifting plate 1133 to move upward along the guide rod 1135. The lifting plate 1133 drives the first clamping shaft 1134 to move upward until it is inserted into the second insertion hole 1242 and continues to push the bucket 122 to move upward. The bucket 122 drives the upper support bar 123 to move upward, so that the second clamping shaft 1211 originally inserted into the first insertion hole 1231 is separated from the first insertion hole 1231. At this time, the frame 121 can be taken out from under the bucket 122, thereby completing the work of transferring the bucket 122 loaded with concrete from the frame 121 to the lifting plate 1133.

[0140] like Figure 7-Figure 9 As shown, the first driving motor 1122 is started, and the first driving motor 1122 drives the conveyor belt 1123 to transmit upwards through the driving roller 1121, and the conveyor belt 1123 drives the limiting guide rod 11232 to move along the track of the guide groove 11241 through the base 11231, and the limiting guide rod 11232 drives the support plate 1131 to transmit upwards obliquely through the fixing block 11233, and the support plate 1131 drives the bucket 122 from the bottom of the bracket 111 to the top of the bracket 111 through the lifting plate 1133 and performs the overturning and unloading work, and the overturned concrete is poured into the guide hopper 131 for caching, and then the guide hopper 131 discharges the concrete into different molds 100 in sequence through the feeding pipe 133, thereby achieving the effect of being able to automatically feed the concrete, without the need to shovel the concrete from the small cart and put it into the specimen mold 100 with a shovel, saving time and labor;

[0141] The present invention directly separates the bucket 122 from the frame 121 and sends it to the guide hopper 131. During the whole process, the concrete is in an integrated state and is not easy to solidify. It is avoided that a large amount of concrete falls outside the specimen mold 100 when the concrete is scooped up by a shovel and put into different molds 100. Once the concrete falls on the ground in a dispersed state, the dispersed concrete is easy to solidify, and it is difficult to make a concrete specimen. Therefore, the present invention adopts a method of separating the bucket 122 from the frame 121, which not only slows down the solidification speed of the concrete, but also avoids a large amount of concrete falling when being loaded into the mold 100, effectively saving a large amount of concrete.

[0142] like Figure 4-Figure 6As shown, in addition, in order to prevent the second plug hole 1242 from being separated from the first clamping shaft 1134 due to the change in the angle of the bucket 122 during the pouring of concrete, thereby causing the bucket 122 to fall off the lifting plate 1133, the present invention, when the cylinder 1132 drives the lifting plate 1133 to move upward, the lifting plate 1133 moves upward along the guide rod 1135, so that the second gear 11344 that was not originally engaged with the teeth on the upper side of the second rack rod 11351 moves to engage with the teeth on the upper side of the second rack rod 11351, so that the second gear 11344 The second rack rod 11351 drives the second gear 11344 to rotate, and the second gear 11344 drives the first pulley 113421 to rotate through the second pulley 11345 under the action of the belt 11343, and the first pulley 113421 drives the first rack rod 11341 through the first gear 11342 to move from being completely located inside the first clamping shaft 1134 to one end being located outside the first clamping shaft 1134, so that the first rack rod 11341 positions the upper end of the lower support bar 124, thereby avoiding the hidden danger of the bucket 122 being separated from the lifting plate 1133 when pouring concrete;

[0143] After the concrete is poured, the first drive motor 1122 is controlled to rotate in the opposite direction, so that the empty bucket 122 is transferred from the upper part of the bracket 111 to the initial position at the lower part by the lifting plate 1133, and the frame 121 is pushed under the empty bucket 122 again, and the cylinder 1132 is controlled to reset, so that the bucket 122 can be reset to the frame 121 again.

[0144] like Figure 11-Figure 14 As shown, during the vibration process of the present invention, initially, the driving gear 227 is meshed with the first tooth portion 212, the arc convex portion 226 is separated from the clamping block 224, and the empty mold 100 is placed on the support 234, so that the second limit block 235 initially limits the two sides of the bottom of the mold 100, and then, the driving mechanism inside the driving seat 232 is started, and the driving mechanism drives the driving seat 232 to move along the guide rail 231, so that the empty mold 100 is driven to the discharge port of the feeding tube 133. In this process, the first tooth portion 212 drives the driving seat 232 to move along the guide rail 231, so that the empty mold 100 is driven to the discharge port of the feeding tube 133. The driving gear 227 rotates, and the driving gear 227 drives the rotating shaft 225 to rotate through the fixed shaft 228. The rotating shaft 225 drives the arc protrusion 226 to press the clamping block 224 against both sides of the mold 100, so that after the mold 100 placed on the support 234 is initially positioned by the second limit block 235, the clamping block 224 can further clamp and position the mold 100, thereby avoiding the position deviation of the mold 100 from the support 234 during the subsequent vibration and smoothing work, which greatly improves the efficiency of vibration and has a good vibration effect.

[0145] like Fig.10As shown, the empty mold 100 is driven to the discharge port of the feeding pipe 133, and the second driving motor 132 is started. The second driving motor 132 drives the mixing paddle 1321 to mix the concrete at the lower opening of the guide hopper 131 and discharge it into the mold 100 through the feeding pipe 133. If the mold 100 is loaded with too much material at one time, the excess concrete will overflow from the mold 100, and the overflowed concrete will be collected by the baffle plate 233 to prevent the overflowed concrete from falling on the guide rail 231, thereby hindering the driving seat 232 from moving along the guide rail 231.

[0146] like Fig.15 As shown, after the mold 100 is filled with concrete, the driving mechanism drives the driving seat 232 to continue to move along the guide rail 231, so that the mold 100 is brought to the right below the vibrating rod 1011, and the vibrating rod 1011 is controlled to extend into the mold 100 to vibrate the concrete. After the vibration is completed, the vibrating rod 1011 moves upward from the mold 100, and the driving mechanism drives the driving seat 232 to continue to move along the guide rail 231 to the right below the smoothing rod 1021. The smoothing rod 1021 moves downward to smooth the upper surface of the vibrated concrete in the mold 100, and then the smoothing rod 1021 moves upward to reset, completing the vibration and smoothing work.

[0147] like Figure 16-Figure 17 As shown, finally, the driving mechanism drives the driving seat 232 to move along the guide rail 231, so that the driving gear 227 moves to mesh with the second tooth portion 213. At this time, the second tooth portion 213 drives the fixed shaft 228 to rotate in the opposite direction through the driving gear 227, and the fixed shaft 228 drives the arc protrusion 226 to reverse through the rotating shaft 225, so that the arc protrusion 226 switches from the original state of pressing the clamping block 224 to the state of separating from the clamping block 224. At this time, the pressing spring 223 presses the first limit block 2221, so that the first limit block 2221 drives the clamping block 224 to separate from the mold 100 through the guide shaft 222. At this time, the mold 100 can be taken out of the support 234 by the manipulator, thereby achieving the effect of being able to automatically position the mold 100 throughout the vibration and smoothing work, and automatically stopping the positioning after the vibration and smoothing work, so that the manipulator can flexibly take out the mold 100 from the support 234;

[0148] After the mold 100 is taken out from the support 234, the driving seat 232 drives the support 234 to move to the initial position, and the next group of molds 100 are placed, positioned, vibrated and smoothed.
